Scientists Test Radical Plan to Thicken Arctic Ice With Seawater

Researchers have successfully trialed an experimental technique that uses seawater to artificially thicken Arctic ice, offering a potential new weapon against climate change. The promising results show the method could slow the dramatic decline of polar ice sheets that threatens ecosystems and global sea levels. However, the approach faces significant practical and logistical hurdles before it could be deployed at scale across the frozen Arctic.
